2-IN-1
DETECTION: Alerts you to both smoke & carbon monoxide (CO) using a single, cost-effective device.
NEVER-CHANGE 10-YEAR BATTERY: No low battery chirps or battery changes for 10 years & saves up to $40 over the life of the detector. (10-yr limited warranty on alarm, not a battery performance claim. )
ENHANCED SENSING TECHNOLOGY: Reduces false smoke alarms often caused by cooking. Comprehensively tested to meet the latest UL standards, meets UL 217 9th Edition, UL 2034 4th Edition, & FCC standards.
VOICE ALERTS: Crystal-clear voice alerts will say Fire! when smoke is detected or Warning! Carbon Monoxide! if CO is detected, so you can react quickly.
SELF-TESTING ALARM: Internal components ensure alarm is always operating as expected. Not a substitute for a manual push test, perform a button test once per week to verify alarm operation.
